44 REPORT OF COMMISSIONERS OF INLAND FISHERIES? 
in the last report, and if the young are not provided with such 
they perish soon after they have escaped from the egg. We have 
succeeded in finding an excellent food, a food that is practically 
the same as that giving nutriment to the embryo while within 
the egg. 
It is a well-known fact that the food-yolk of the lobster’s egg 
is finally stored in the liver of the growing embryo, and at the 
time of hatching the supply of this material is nearly exhausted. 
The liver of the adult lobster, (the greenish-colored gland, so 
delicious to the taste, and often called the “ fat,”’) is made up of a 
number of short fibres, which may be readily cut up into morsels 
practically microscopic. These float about in the water and are 
easily devoured by the fry, a single liver being sufficient to feed 
many thousands. As soon as the lobsters leave the hatching-jars, 
they are placed in Chester jars, the water of which is kept in ac- 
tive movement, and a small quantity of the subdivided liver is 
added. In ashort time the lobsters appear to have changed in 
color, but a more careful examination will show that the change 
is only apparent, and not real. It is due to the presence within 
the stomach and intestine of the yellow-fat-bearing food, which 
can be seen easily through the transparent body-walls, and which 
often marks out the shape and extent of the entire alimentary 
tract. So characteristically does it mark the animals that have 
fed that they may be removed from their less active, mjured, 
sluggish, or indifferent companions, and placed where they will 
have more room and a more natural environment than the whirl 
of the hatchery. 
It is our opinion that, thus artificially fed, the young are not so 
prone to feed upon one another as those starved into cannibalism, 
and we feel convinced that the food is a determining factor m the 
problem of brooding. 
We have found that the most suitable enclosure is a ear, not 
with rigid walls of wood, wire, or scrim, but rather a large bag of 
scrim made after the fashion of a fish-pocket, and hanging down 
into the water from a square floating frame. The bag waves back
